My overall experience was very positive. All the interviewers were very cool which helped me to few comfortable during the whole process. My process took 4 steps, about 4 to 3 weeks. First step was a call with recruiter, second was a 1 hour hangout interview with Engineering Manager, the third step was a code challenge to be done using Vert.x. fourth step was a code review with 2 software engineers. I didn't pass to the next step.
